Just noting that Dushan loves everyone equally. Thusly, nobody is exempt from collective familial activities, ever, period. If he drags the entire castle out into the forest to hunt wolves, there are two possible outcomes - either absolutely everyone is present or absolutely everyone suffers his stern fatherly wrath. Courtiers included. Everyone who has a permanent position in the castle attends the dinner at 2 AM and not a minute later unless they are abroad on a spiritual quest or something. Now, who wants their character to be especially close to Dushan on the grounds of sharing some particular hobbies or interests or history together? He travels a lot and during the times he was leaving anyone willing to accompany him was welcome for most of the time.
